ASUS A8N32-SLI Deluxe Motherboard @ NordicHardware

Snip: Instead of a bunch of noisy fans, ASUS has opted for a heatpipe solution, leading away the heat from both the north- and southbridge to a larger heatsink right next to to CPU socket. This heatsink also cools one cluster of the power solution’s MOSFETs and due to its proximity to the CPU heatsink it gets an adequate airflow. The second cluster sits beneath another heatsink just above the CPU socket.
